CORK-MACHIN E.

Specification of Letters Patent No. 17,557, dated June 16, 1857.

To all whom it may concern:

Be it known that I, EDWARD Connor, of South Boston, in the county ofSuffolk and State of Massachusetts, have invented a. new and ImprovedImplement or Device for Cutting Corks or Bungs; and I do hereby.

declare that the following is a full, clear. and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which Figure 1, is a vertical section of myimprovement; the plane of section passing through the center. Fig. 2, isan inverted plan or face view of the cutting device. Fig. 3, is ahorizontal section of ditto; (m), (00), Fig. 1, showing the plane ofsection.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an improved construction of cutter head inwhich expanding cutters are used and operated in a simple or novelmanner by the stuff as it is fed to the cutters. The cutters, inconsequence of their gradual expansion, cutting the corks or bungs fromthe stuff in conical form, with the greatest facility and with a smallexpenditure of power.

The invention also relates to the means employed for feeding the stuffto the cutter head, when said means are used in connection with thecutter head, as will be herein after described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents a rectangular framing which may be constructed in anyproper manner to support the working parts.

B, represents the driving or power shaft which is placed on the upperpart of the framing A; and C, is a shaft placed in the lower part of theframing and driven from the shaft B, by a belt D. On the shaft C, abevel pinion E, is placed, and this pinion E, gears into a wheel F,which is placed. on the inner end of a shaft G, which is placedlongitudinally within the framing A, and

somewhat inclined. On the outer end of the shaft C, a screw H, isplaced, and this screw gears into a main wheel I, on a shaft J, which isparallel with the shafts B, C. At each end of the shaft J, an eccentricor cam K, is placed, and on these eccentrics or cams a horizontal bed L,rests, said bed having a pendent at each end, the pendent fitting ingrooves in the framing and serving as guides for the bed.

M, represents a vertical arbor which is fitted in suitable bearings atone end of the framing A, directly over the bed L, at about its center.The arbor M, is driven by a belt (1)), from the driving or power shaftB.

N, is a rod which is fitted vertically in the lower part of the arbor M,and has a pin (a), passing transversely through its upper part; said pinworking in slots (J), in the sides of the arbor and serving as a guidefor the rod N, (see Fig. A spiral spring (0), is fitted within thearborM, and bears against its upper end. A collar 0, is placed on thearbor M, and is connected to the rod N, by a pin (f), which passestransversely through the rod and also through the slots (cl), in thesides of the arbor M.

P, P, representrods at the lower ends of which cutters (f) are attachedor formed. The upper ends of the rods P, have pins (9), passingtransversely through them, a pin passing through each rod, and thesepins are fitted in recesses (71), atopposite sides of the arbor M. Toopposite sides of the collar O, springs Q, are attached, and the lowerends of these springs bear or rest against the rods P.

R, represents a plate, the sides of which are inclined or beveled. Thisplate passes through the rod N, and the sides of the plate R, bearagainst the inner sides of the rods P, as shown clearly in Fig. 1.

Itwill be understood that the pins (9), of the rods P, are allowed towork laterally in the recesses (h). The lower end of the arbor M, has aflanch 0 around it; said flanch having slots (2'), made through it,through which the rods P pass.

To each end of the bed L, a spiral spring S is attached.

The operation is as follows: The stuff shown by dotted lines from whichthe corks or bungs are cut, is placed on the bed L, and motion is giventhe power shaft B, in any proper manner. The arbor M, is rotated by thebelt (1)), and the bed L, is moved up ward, and the stuff consequentlyfed to the cutters (f (f by the cams K. The stuff bears against thelowerend of the rod N, and

horizontally or nearly so, as the pins (9),

are allowed to move laterally in their re cesses (h) the cutters (f (fowing to their rotating motion and their lateral movement, cut the corksor bungs in conical form, the sides of the corks or bungsbeingiperfectly straight and not of curved or concave form. l/Vhen theprominent portions of the cams have'passed the bed L, the bed isdepressed or brought back to its original position by the springs S. Thecams, of

course, are so formed that they will feed the 7 stuff upward therequisite height in order that the cutters will cut through the stuff.

I do not claim the employment or use of expanding cutters, for cuttingcorks, bungs, etc, irrespective of the arrangement herein shown,for-expanding cutters have been pre- Viously used, although differentlyarranged from the plan herein shown; but,

Having thus described my invention, what I claim as new, and desire tosecure by Letters-Patent, is: I

1. The expanding cutters attached to the rods or bars P, and operated bythe plate R, attached to the rod N; the rods P, having pins (9), passingthrough their upper ends, which pins are allowed to slide laterally intheir recesses (h), as the rods are actuated by the plate R, the aboveparts being arranged substantially as herein described, for the purposeset forth.

I further claim, in "combination with the cutters (7) arranged andoperated as shown, the cams K, and bed L, for feeding the stuff to thecutters.

EDWVARD CONROY.
